Default Guys who have modded their injector offset values...

Right now, I'm still running the PCM's stock injector offset values with the SVO 42# injectors. I'm seeing about an 8% difference between part throttle(-5%) and idle(+3%) LTerms.

I have my tune about 90% done. All I need to tweek is the WOT A/F ratio and a little timing here and there. Other than that it runs great. All the hot start issues, bucking, wanting to die, ect are gone.

Question is, if I now change the injector offset values, will this throw off most of the other changes I have made?

Specifically:
PE vs. RPM
Main VE(for cam)
Injector Flow Rates
Running Airflow(for cam)*
Park Position Airflow(for cam)*
P/N Airflow Decay(for cam)*
* I dont think the changed offset will affect this, but I'm not sure

I knew I should have listened to probably the most important piece of advice I was told.... "Install and tune the injectors first, before putting on the sc." Probably would have saved me a lot of time invested.
Thanks,
